The genus Psychotria is well known as a source of alkaloids and has contributed several novel indole-type alkaloids with quite a broad spectrum of bioactivities. This study was focused on identifying the alkaloids from the leaves of P. malayana Jack from Lombok island on the basis of Gas Chromatography-Mass Spectroscopy (GC-MS) data and the sample preparation followed acid-base extraction. The study showed that the major alkaloid contained by the leaves was hodgkinsine and other minor compounds, namely calycanthine, chimonantine, 2-ethyl-6-methylpyrazine, and 3-methyl-1,2,3,4-tetrahydrogamma-carboline. Bioactivities of the compounds were also discussed.
This activity is presented to handle waste as well as to improve public health by utilizing medicinal raw materials that have not been used optimally by the community into food or beverages that are pleasant to consume. This service was carried out in Gegelang Village, Lingsar District, West Lombok, in collaboration with the local village PKK driving team. The target of this service is the village community, especially mothers who are the heart of the family who serve food in the middle of the family every day. This service was carried out in the early months of February 2022. Community service received a positive response from the community, as evidenced by a high level of satisfaction. Furthermore, this service activity succeeded in inviting the community to use mangosteen peel extract for food additives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
